Question 1 of 5
A nurse is reinforcing teaching with the parents of a child who is starting to use a spacer with a metered-dose inhaler (MDI) to treat asthma. Which of the following information should the nurse include in the teaching?
Correct Answer: C
Rationale: The primary purpose of the spacer is to increase the amount of medication that reaches the lungs and to reduce the amount deposited in the oropharynx (throat). The spacer helps to ensure that more medication is delivered directly to the airways where it is needed, thereby enhancing the effectiveness of the treatment and reducing side effects.
Question 2 of 5
What type of cells secrete glucagon?
Correct Answer: D
Rationale: Alpha cells, also known as A cells, are a type of pancreatic islet cell that secretes glucagon.
Question 3 of 5
A patient is admitted to a respiratory unit with a diagnosis of bacterial pneumonia. Findings include a fever and a weak, congested-sounding cough with moist crackles throughout the lung fields. How should the nurse prioritize care?
Correct Answer: B
Rationale: The inability to clear the airway is a critical issue. This patient has a weak, congested-sounding cough and moist crackles, indicating that secretions are present and not being effectively cleared. This can lead to airway obstruction, decreased oxygenation, and further respiratory complications. Clearing the airway is a top priority to ensure the patient can breathe properly and prevent further deterioration.
Question 4 of 5
Management of asthma involves avoidance of triggers. Which environmental triggers will the nurse suggest the patient eliminate? Select all that apply.
Correct Answer: B,C,D,E
Rationale: B. Beta-blocking medications can worsen asthma symptoms by constricting the airways. C. Exposure to secondhand smoke is a well-established trigger for asthma symptoms. D. Carpeting and drapes can harbor dust mites, pet dander, and other allergens. E. Pets can be potent allergens for individuals with asthma.

Question 5 of 5
The nurse recognizes the patient is demonstrating signs of diabetic ketoacidosis (DKA). Which findings support this recognition? Select all that apply.
Correct Answer: A,C,F,G
Rationale: A. Acetone breath, characterized by a fruity or acetone-like odor on the patient's breath, is a classic sign of DKA. In addition, Kussmaul respirations, which are deep and labored breathing patterns, can occur as the body attempts to compensate for metabolic acidosis in DKA. C. Nausea and vomiting are common symptoms of DKA and can occur due to metabolic acidosis, electrolyte imbalances, and gastrointestinal disturbances associated with the condition. F. Tachycardia and hypotension are signs of hemodynamic instability, which can occur in severe cases of DKA due to dehydration, electrolyte imbalances, and the systemic effects of metabolic acidosis. G. Turning off an insulin pump can lead to insulin deficiency, which is a precipitating factor for DKA, particularly in patients with type 1 diabetes who rely on continuous insulin therapy.
